Portable apparatus and associated methods

Portable apparatus such as a hair styling device comprises a power source 21 (e.g. PSU) an energy storage means 22 (e.g. capacitor) and an electrical component 23A, 23B (e.g. heater). The power source 21 is configured to charge the energy storage means 22 via the electrical component 23A, 23B. Preferably, control circuitry is configured firstly to output power from the power source to the electrical component and to the electrical storage means via the component, and secondly to output power to the electrical component as the energy storage means outputs power to the electrical component. Variable power demand from the electrical component influences whether the device is used in the first or second configuration. Where the electrical component is a heater and the energy storage means is a capacitor, the power source is able to charge the capacitor via a first heater electrode 231A, 231B. The capacitor may discharge via a second heater electrode 232A, 232B. Heat dissipated when charging the capacitor from the power source is thus output as useful heat via the first electrode.
